Semantic Search for COVID-19 Using Twitter


How To Use
Instructions

To compose a search query, simply fill in zero or more text filters that constrain your search. Next, you can enter a "?" to indicate how the extracted tweets should be grouped. The demo will return a list of all unique answers for the field marked with "?", sorted by frequency.

We also provide a video for demonstrating how to use our demo (click "video" icon or scroll down to the bottom of the page).

Sample Queries

Here we provide sample results for some example queries with methods to generate them.
Example 1. Who tested positive? [This query is generated by putting "?" in "name" slot.]
Example 2. Where did people test positive? [This query is generated by putting "?" in "where" slot.]
Example 3. Who tested positive that had close contact with Boris Johnson? [This query is generated by putting "?" in "name" slot and "Boris Johnson" in "close contact" slot.]

We recommend using Chrome to get our demo work properly.
